复方连翘口服液中钩藤碱的鉴定研究

Qualification Research of the Rhynchopylline in the Forsythia Oral Liquid of Medicine Made of two or more Ingredients

目的鉴定钩藤碱为复方连翘口服液中的主要成分。方法用碱化醚提取法提取复方连翘口服液中的主要成分钩藤碱与生药钩藤之钩藤碱。再用熔点测定、光谱分析等鉴定两钩藤碱的特征。结果与结论两碱性的理化检测鉴定结果显示:从性状、熔点、薄层板析斑点、与碘化铋钾的反应、光谱分析的特征峰及化学结构均呈现完全一致。

Objective Determine that the rhynchopylline is a backbone in the forsythia oral liquid of medicine made of two or more ingredients Method With alkalize ether draw law draw medicine made of two or more ingredients forsythia backbone hook rattan and crude drug hook rattan alkali bbof oral liquid . Use and melt a little more and deteimine. Spectral analysis, etc appraise the characteristic of two hook rattan alkli. Result and Conclusion Two alkaline physics and chemistry measure and determine that the result shows:Analyse spot from properties, point, thin plywood,bismuth response,characteristic peak and chemical constitution of spectral analysis of potassium appear at all unanimous with iodine.
